CLV is a disk coated with a metal thin film that forms a concavo-convex portion that provides different light reflectance depending on @0#.
Approximately 500 to 200 r, p depending on the (constant linear velocity) method
, m, and is reproduced in a linear tracking manner from the inner circumferential side to the outer circumferential side using an optical pickup containing a semiconductor laser and a photoelectric conversion element.

In this case, CDs have a huge amount of information recorded on them, allowing for approximately one hour of stereo playback on one side, and have a higher recording density than conventional analog discs in terms of playback characteristics. It has been established in principle that it can be made significantly superior in terms of points as well.

By the way, these CDs have excellent features.

One way to utilize this feature is, for example, in a multi-disc automatic performance device for professional use.

In other words, this corresponds to a so-called jukebox or karaoke device which is also put into practical use with analog discs, and can be realized by a disc autochanger device.

However, this type of disc autochanger device that has been known in the past has a complex structure and large size, partly because it is intended for analog discs, so it has problems in terms of operability. There was a problem. In addition, due to the need for reliable operation, the number of discs that can be stored cannot be increased that much, and the speed at which discs can be replaced cannot be made that fast.

Therefore, there are many problems in applying the conventional disc autochanger device for CDs as described above, and it is an urgent issue to develop a disc autochanger device suitable for CDs. It had been.

Incidentally, this situation is the same in the case of laser video discs, and also in the case of application to optical disc file systems that have recently been put into practical use as part of so-called electronic file conversion.

[Purpose of the invention]

Therefore, the present invention has been made in view of the above points, and is designed to make it possible to increase the number of discs that can be stored with as little space as possible, and also to contribute to improving the disc exchange speed. Moreover, it is an object of the present invention to provide a highly efficient disc autochanger device that satisfies the requirement of reliable operation with a simple configuration.

[Summary of the invention]

That is, the present invention provides a disc autochanger device that can automatically select a predetermined disc from a tray and supply it to a disc playing section for exchange, in which the disc playing section is moved in accordance with the disc selected by the tray. A search wire supported at both ends and this...
a power pulley around which the middle part of the chain wire is wound and which is movably provided in the axial direction on the disk playing section; a drive mechanism for rotationally driving the power pulley; The invention is characterized in that it includes a braking mechanism that applies braking by moving in the axial direction, and returns to the light position in a selected state to release the braking.

[Embodiments of the invention]

Hereinafter, as an embodiment of the present invention, a case where the present invention is applied to a multi-disc automatic performance apparatus for CDs will be described in detail with reference to the drawings.

FIG. 1 shows a front external view of a cabinet 100 that houses a disc autochanger mechanism to be described later, in which 101 is a main tray storage section that can accommodate a large number of discs (60 discs in this case), and 102 is a main tray storage section that can accommodate a large number of discs (60 discs in this case). This is an auxiliary tray storage section that can be called a glass one tray to allow a small number of disks (in this case, one disk) to be freely inserted and removed.

In addition, 103 is an operation section for specifying the performance status such as starting, pausing, canceling, and redoing the performance, 104 is a key operation section and its display section that allows reservation of up to 5 songs in this case, 10
5 is a display section for song pitch (tempo) control and key control; 106 is a display section for signal level; lθ
7 is a ten (10) key operation section, 10B is a display section for the song currently being played, and 109 is a display section for the next song to be played.

Note that 11O is a headphone plug insertion part, 11 is a remote control plug insertion part, and 112 is an operation part for inserting and removing the auxiliary tray.

FIGS. 2 and 3 show a perspective view and a plan view of the disc autochanger mechanism taken out of the cabinet 100 shown in FIG. The main tray mechanism section 200 is installed in such a manner.
, an auxiliary tray mechanism section 300 and a disc search performance mechanism section 400.

To roughly explain the operation of such an autochanger mechanism, the main tray mechanism section 200 (main tray mechanism section 200) has a predetermined number of disks 201 stored in advance in disk storage grooves 203 of a tray body 202, which will be described later, in a vertical line at a predetermined pitch. or auxiliary tray mechanism section 300), the disk search performance mechanism section 400 first searches for the target disk 201 by moving in the directions of arrows (A) and (B) shown in the figure based on the disk access information. After taking out the disc 20 and putting it into a playing state, then after playing the disc 201, the main tray mechanism section 200 or the auxiliary tray mechanism section ? After returning to the original position on 00, the same operation as described above is repeated based on the next 7-' access information.

In this case, the king tray mechanism section 200 performs the synthesis (q
The tray main body 202 made of 1-fat resin is placed on the left and right tray supports 253 and 254 erected on the main 7 palms 121,
It is supported in a detachable manner as will be described later.

In addition, the auxiliary tray mechanism section 300 has its auxiliary tray 301
is supported by an auxiliary tray drive mechanism 350, which will be described later, so that it can move in and out in the directions of arrows (C) and (D) in the figure.

Further, the disc search performance mechanism section 400 includes a disc search section 500 and a disc transport mechanism section 6, which will be described later.
00 and the disc performance mechanism section 700 are integrated into a unit, and the main chassis 1
It is moved in the directions of arrows (A) and (B) shown in the figure by the driving force of a search wire 403, which will be described later, using a rail 401 and a guide shaft 402 supported by two wheels as guides.

In addition, 404 in FIG. 3 is a synthetic resin address plate supported on the main chassis 121, and is formed in the tray body 202 of the main tray mechanism section 200, in this case 60 disk storage grooves 2θ3. A binary pattern is formed that allows optical detection of one-to-one absolute addresses. However, the support structure for the address plate 404 with respect to the main chassis 121 will be described later.

Next, details of each of the above parts will be explained in order.

FIG. 4(,) shows the main tray mechanism part in the above, including a tray main body 202 having 60 disk storage grooves 203 in the shape of approximately 1/4 semicircle, and A spring 204 is rotatably mounted between both sides of the
U-shaped disc hold lever 2 supported through
05, and attachment/detachment guide portions 206 similarly formed on both sides.
, and 60 positioning slits 207 formed corresponding to each entrance/exit portion of the disc storage groove 203 as shown in FIG. 2(b).

5(a), (b), and (e) are a cross-sectional side view, a side view, and a front view showing details of the tray main body 202, each with a radius of curvature (R+) suitable for the disk 201 to be accommodated. is a valley and has a mountain portion of a predetermined shape as described later, that is, a partition wall 20B of a predetermined height, and is approximately 1/4
Sixty semicircular disk storage grooves 203 are arranged at a predetermined pitch in the longitudinal direction (in the case shown, 4 mm for a CD with a 1.2 scale thickness, however, the valley width at the entrance is 1.4 mm). The width of the valley at the inner part is 2.8 mm wide at the end), and a notch 209 and a locking part 210 are formed at the bottom of each disc storage groove 203. The above-mentioned slit 207 is formed at each entrance/exit portion.

Here, the partition wall 208 of the disk storage groove 203 is arranged in the storage direction of the disk 201 so as to prevent the tip of the disk 201 from hitting the top of the partition wall 208 and becoming unable to store the disk 201 when the disk 201 is being stored. The height of each part is set.

That is, the disk 201 is accommodated while slidingly contacting the bottom of the groove in the direction of the arrow (E) shown in the figure, but the partition wall 20
If we do not consider the height of g, when the disc 201 is tilted in the direction perpendicular to the storage direction in the disc storage groove 203, the tip of the disc 201 will be at the top of the partition wall 208 at that position. I can't help but draw it.

Therefore, the top of each part of the partition wall 208 is connected to the disk 2.
01 at each position in the storage direction (P
) If it is set so that it has a radius of curvature larger than that of the disk 201, the disk can be positioned on a line that slopes outward from the tangent line (Q) of 201 can be stored smoothly.

Note that 209 in FIG. 4 is a notch for pushing up the disk formed in connection with the bottom of each disc storage groove 203, and 210 is a j-ray body lock formed on one side of the notch 209. The details of these step-shaped locking portions will be described later.

Further, 270 is a drawer section which will be described later.

FIG. 6 is an exploded perspective view for explaining the procedure for attaching and detaching the main tray mechanism section 200 as described above. , tray body 202
The attachment/detachment guide portions 206 formed on both 9ili portions may be inserted in the direction of the arrow (F) shown in the figure.

However, in this case, before insertion, the disc hold lever 205 is in the position shown by the solid line, rotated in the direction of the arrow (G) by the biasing force of the spring 204, and any disc 201 is inadvertently moved from the tray main body 202. This makes it possible to prevent them from falling off.

During the insertion process in the direction of the arrow (F), the disk hold lever 205 has its both end locking portions 257 attached to the lock bins 253 and 254 provided on the tray supports 253 and 254.
8.259 and is rotated in the direction of the arrow (b) shown in the figure so as to be at the position shown by the thin line in the figure, and is locked at the final position in the insertion direction.

FIG. 7 is a progress diagram for explaining such an insertion (locked) state, in which (,) indicates the above-mentioned arrow (During the insertion process in the F5 direction, the disc hold lever 205(r) locking portion 257
is in contact with the lock bins 258 and 259. (
b) is a state in which the locking portion 257 passes between the lock bins 258 and 259 by further insertion, and the disc hold lever 205 is rotated in the direction of the arrow θ () shown in the figure. (Q shows a state in which the locking portion 257 of the disc hold lever 2os is engaged with the lock bin 258 and locked by the biasing force of the spring 204 as the disc is further inserted.

When the installation of the main tray mechanism section 200 is completed, the disk hold lever 205 is opened as shown in FIG.
is rotated to a position corresponding to the position indicated by the chain line in FIG. 6, so that the disks 201 stored in the main tray mechanism section 200 can be selectively taken in and out.

When this installation is completed, as shown in FIGS. 6 and 8, the roller 261 supported at the tip of the tray presser lever -260 provided on the back side of the tray support stand 253 (flit) will move to the window 253a. Because the tray body 202 has penetrated further, the tip of the attachment/detachment guide part 206 of the tray body 202 is pressed in the direction of arrow (I) in the figure by the biasing force of the spring 262, and is also pushed in the X-shape by the spring 267. A pair of engaged tray horizontal presser levers 263 and 26
Since the rollers 265 and 266 supported at each tip of the tray body 202 enter through the windows 253b and 253c, the corresponding side edges of the tray body 202 are pressed in the direction of the arrow (J) shown in the figure.

As a result, the installation of the main tray mechanism section 200 is completed as shown in FIGS. 2 and 3, and in this installation completion state, it is fixed without wobbling due to the above-mentioned locking action and suppressing action. It turns out.

By fixing the main tray mechanism section 200, the tray main body 202 is thermally maintained as shown in FIG.

The left end side is made to be expandable and retractable with the right end side in FIG. 3 as a reference.

Further, since the address plate 404 needs to be supported in a one-to-one relationship with each disk storage groove 203 and slit 207 of the tray body 202, it is attached to the main chassis 121 as shown in FIGS. 2 and 8. On the other hand, leaf spring 2
68 and a buffer member 269 such as rubber, the right end side is thermally supported so that it can expand and contract with the left end side as a reference.

This allows even if there is a change in ambient temperature,
If the tray main body 202 and the address plate 404 are made of materials having the same thermal properties, such as the same type of synthetic resin, each disk storage groove 203 and slit 207 of the tray main body 202 and the address plate The nine turns for absolute address detection of 404 maintain a one-to-one relationship due to thermal expansion and contraction, so that accurate address detection (access) and positioning as described later can be performed at all times. It is something that is being done.

When the main tray mechanism section 200 is to be slid out from the main body, first, in order to release the above-mentioned locked state, the disc hold lever 205, which is located at the solid line position shown in FIGS. 8 and 10, is pressed. After pressing the lever 205 slightly downward, put your hand on the drawer part 270 formed at the bottom of the tray body 202 and pull it out in the direction indicated by the arrow opposite to the insertion direction.

FIG. 9 is a progress diagram illustrating the state of pulling out and unlocking the disc lever 205.
Immediately after pushing down the lever 2 in the direction of the arrow (6) shown in the figure,
This is a state in which the engagement between the locking portion 257 of 05 and the lock bin 258 is released.

(b) shows a state in which the tray main body 202 is pulled out in the direction of the arrow (L) in the figure, so that the locking portion 257 of the lever 205 passes between the lock bins 258 and 259, allowing the tray body 202 to be pulled out in the same direction.

When the main tray mechanism section 200 has been completely pulled out, the disk hold lever 205 is moved by the spring 2.
Due to the biasing force of 04, the position of the chain line in Fig.
The solid line in the figure indicates that the disk 201 will be returned to the position indicated by the solid line when it is pulled out and after it is pulled out.
It is possible to prevent it from accidentally falling off.

In addition, in the process of such a pulling operation, if the king tray mechanism section 200 is made to be able to be pulled out while the f-isk hold lever 205 is pressed down in the direction of the arrow (8) shown in the figure, the lever 205 One reason why the effect of preventing the disc from falling off during withdrawal cannot be achieved is that in reality, as described above, during the withdrawal process, the locking portion 257 of the lever 205 locks into the lock bin 259 as shown in FIG. 7(a).
10, the lever 205 is forcibly released from the hand, allowing the lever 205 to rotate in the direction of the arrow (G) in the figure, and as shown in FIG. The device returns to the solid line A device, and the effect of preventing the disk from falling off can be reliably achieved.

As described above, it becomes possible to stably attach and detach the main tray mechanism section 200.

By the way, in the case of tomashing, the disk 20 may inadvertently fall off from the tray body 202 due to external vibrations applied to the body while the tray mechanism part W is installed in the body. There is a risk that it will happen.

For this reason, as shown in FIG. 11, a disc stop wire 406 whose both ends are locked to the front end of the disc search performance mechanism section 400 via a spring 405 is attached to the pulleys 407 and 4 supported by the side chassis 122 and 123.
0B and 409.410 in a loop shape, the disc stop wire 406 can be held in any position no matter what position the disc search performance mechanism section 400 is moved in the directions of the arrows (A) and (B) shown in the figure. Since it is linked to this, it is opposed to any disk 201 stored in No. 202 (see Figure 3).
Thus, it is possible to prevent the disc from accidentally falling out of the main body.

Note that when any of the discs 201 stored in the main tray mechanism section 200 is being searched and played by the disc search performance mechanism section 400 as described later, the main tray mechanism section 200 cannot be inserted or removed. ing.

FIG. 13 shows the auxiliary tray mechanism section 300 taken out from above, and in the case of , the auxiliary tray, 90
J is shown pulled out in the direction of arrow (C) in the figure.

That is, in this case, the auxiliary tray 301 has a disc storage groove 302 in the shape of approximately 1/4 semicircle at the front, which can store one disc 201, and an auxiliary tray chassis 303 at the rear. The guide shaft 304 and the lower rail are made of resin or the like, and the auxiliary tray chassis 303 is vertically arranged near the right side chassis 12s. 05, sliding bearings 306, , ? 07 and roller 3
The auxiliary tray chassis 30 is slidably supported in the direction of the illustrated arrow (C'l) through
The rack 309 part integrally formed on the back side of 3 is an auxiliary tray drive mechanism, which will be described later. 50, the auxiliary tray can be automatically pulled out and pulled in from the main body in response to the first and second operations of operation parts 1 and 2 for loading and unloading the auxiliary tray shown in FIG. It is done freely.

When the auxiliary tray 301 is pulled out as shown in FIG. 13, the disk stop lever 310 is rotated so as to be positioned at the rear of the disk storage groove 302, as will be described later, so that the disk 201 is moved backwards. It is designed to prevent it from falling off to the side.

- In FIG. 13, the auxiliary tray 301 has a notch 380 for pushing up the disc continuous to the bottom of the disc storage groove 302 mentioned above, and a step-shaped notch 980 on one side of the notch 980 for locking the auxiliary tray. A locking portion 38 is formed, the details of which will be described later.

The height of each part of the partition wall 382 of the disc storage groove 302 formed in the auxiliary tray 301 is the same as that of the partition wall 208 of the disc storage groove 203 formed in the tray body 202 of the main tray mechanism part 200 described above. shall be taken into consideration.

Further, the entrance/exit part of the disc storage groove 302 formed in the auxiliary tray 301 (the far side in FIG. 13) is formed at the entrance/exit part of the disc storage groove 203 formed in the tray body 202 of the main tray mechanism section 200 described above. It is assumed that a slit (not shown) similar to the positioning slit 207 is formed.

FIG. 14 shows a detailed diagram of the auxiliary tray drive mechanism 350, in which the driving force from the motor 35 is transferred from the worm gear 352 to the worm wheel gear 353 to the clutch gear 3.
54→first gear 355→second gear 356→third gear 357→fourth gear 358. The signal is transmitted to a rack 309 that is integrated with 03.

Here, the clutch gear 3 inserted in the power transmission path
54 is for limiting the maximum torque finally transmitted to the rack 309 to prevent undesired jamming between the worm gear 352 and the worm wheel gear 353.

FIGS. 15(a) and 15(b) show the disk stop lever 3JO section taken out. Now, as the motor 351 of the auxiliary tray drive mechanism 350 rotates, the auxiliary tray 301 moves as indicated by the arrow in the figure. D) Assume that the object is pulled in the direction.

That is, in the case of , as described above, before the start of the retracting operation, the disk strike tool 7', lever, ?, which is rotatably supported by the rear part of the auxiliary tray soi, 1
0 has one end in contact with the stopper 312 by the biasing force of the spring 31, and the other end is located at the rear of the disc storage groove 3θ2, that is, facing the disc entrance/exit part.

When the retracting operation is performed, the row 2 supported by one end of the disc stop lever 310 in the process
313 comes into sliding contact with the inclined part of the swash plate cam, 9 no.
It is often rotated in the counterclockwise direction of arrow (6) shown in the figure against the biasing force of.

As a result, when the retracting operation is completed, the other end of the disc stop lever 310 is moved away from the disc storage groove of the auxiliary tray 3θI and the rear of the disc 902, as shown in FIGS. 16(a) and 16(b). Since the disc 20 is located in a position not facing the disc 20, it is possible to insert and remove the disc 20 by a disc search performance mechanism section 400, which will be described later. Even when the auxiliary tray 301 is retracted in this way, the disc stop wire 409 prevents the disc 201 stored in the disc storage groove 302 from accidentally falling out of the main body. .

Furthermore, it goes without saying that when the auxiliary tray 30 is pulled out, the path opposite to that described above is followed and the state shown in FIG. 13 is finally reached.
When the disc 2θ1 stored in the auxiliary tray 30 is being searched and played by the disc search performance mechanism section 400 as described later, the auxiliary tray 30 cannot be inserted or removed, as in the case of the main tray mechanism section 200 described above. It is said that

In this case, the disc 201 stored in the auxiliary tray mechanism section 300 is searched and put into the playing state only after the disc search and playing mechanism is put into the driving state as described below. However, if this occurred before or during the retracting operation of the auxiliary tray 301, it would become impossible to search for the disc 201 stored in the auxiliary tray 301 and to enter the playing state.
This tends to cause malfunctions.

For this reason, such an auxiliary tray 30 as shown in FIG.
A priority circuit 370 is provided so that the operation by the auxiliary tray loading/unloading operation section 112 (see FIG. 1) is given priority over the access start specifying operation section 1o3 (see FIG. 1) for the disk 201'' stored in the storage space. Drive control circuit 3 through
The configuration is such that a start signal is supplied to 71. This allows the auxiliary tray loading/unloading operation section 112 to be operated for the first time (
When there is an operation (withdrawal), the time spent on retraction after the second (retraction) operation is determined by the start signal from the access start designation operation unit 103 from the drive control circuit. 7 J, the operation of the auxiliary tray loading/unloading operation section 112 has priority over the operation of the access start designation operation section 103, and the operation of the auxiliary tray 301 is prevented from occurring without causing the above-mentioned malfunction. Searching and playing operations for the stored disc 201 can be performed reliably.

In other words, in this case, the differential search performance mechanism section 401 must be completely pulled into the predetermined position within the main body by the auxiliary tray drive mechanism 350.
It is designed so that the motor does not become in a driving state.

The auxiliary tray detection switch 372 in FIG. 17 is, for example, a microswitch provided at the rear of the side chassis 123 in FIG. The above-mentioned malfunction can also be prevented by allowing reception of a start signal by operating the access start designation operation unit 103 after detecting the end of OJ retraction.

FIG. 18 shows a conceptual diagram of the disc autochanger device as described above, in which each operating section J as shown in FIG.
O,? , 104, J05.

Based on various operation command signals from the operating section 910 including the main tray 107, the mechanical sections 350, 400 are driven to a predetermined state via a control circuit 920 consisting of a microcontroller, etc. A desired disc 201 is automatically exchanged and played from the mechanism section 200 or the auxiliary tray mechanism section 300.

The display section 930 in FIG. 18 includes display sections 104, 105, 106, 108, 109, etc. as shown in FIG.

Next, the features of the main tray mechanism section 200 and reinforcement tray mechanism section 300 as described above will be explained.

First, regarding the structure of the tray main body 202 or the auxiliary tray 30, it has a disk storage groove 203-'J or a disk storage groove 302 that holds approximately 1/4 semicircumference of the disk 201. However, the top of each part of these partition walls 208f or 382 is connected to the disk 20.
An example of this is that each position in the first storage direction is set to be located on a line that is inclined outward from a tangent to the outer circumferential circle of the disk space.

In other words, this prevents the tip of the disc 20 from hitting the top of the partition wall 208 or 382 when storing the disc 201, making it impossible to store the disc 201. This is because it can contribute.

The second point is that the main tray mechanism section 20θ, which is detachable from the main body, assumes a first position that commonly prevents the disk 201 from falling from the tray main body 202 when removed from the main body, and A disk holding member such as a disk hold lever 205 is provided which assumes a second position that allows the disks 20 to be selectively taken in and out of the tray body 2θ2 while mounted inside the tray body 2θ2. Can be mentioned.

In other words, this allows the main tray mechanism section 2 to be removed from the main body.
This is because it is possible to prevent the disc 201 from accidentally dropping when the disc 201 is removed, and also allows the disc 201 to be selectively taken in and out when it is installed in the main body.

The third point is also related to the main tray mechanism section 200, by locking the disk hold lever 205 (D) when inserted into the main body with a locking member such as By making the disc 201 unremovable, it is possible to prevent an accidental detachment from occurring, which in turn contributes to preventing the disc 201 from falling.

The fourth point is also regarding the support structure of the main tray mechanism section 200, so that it has the same thermal conditions as the support structure of the address detection member such as the address plate 404 for address detection, with one side as a reference. By making the other side thermally expandable, accurate address detection (access) and positioning are possible at all times.

The fifth point is regarding the main tray mechanism section 200 and the auxiliary tray mechanism section 300, when both are placed in predetermined positions in the main body, the disks are placed opposite to the loading/unloading side of each disk 201 stored therein. Both ends of the stop wire 409f are connected to the disk search performance mechanism h40
The point is that it is stretched in a luzo-like manner so that it can run freely when it is locked to 6.

That is, this is because the disc 201 can be prevented from accidentally falling off from the tray main body 202 or the auxiliary tray 301 within the main body.

The sixth point relates to the auxiliary tray mechanism section 200, and a disk stop lever 310 that faces or does not face the disk loading/unloading side of the auxiliary tray mechanism in conjunction with the auxiliary tray mechanism section 200 being moved in and out of the main body. One point is the provision of a disc stop like this.

In other words, the auxiliary tray mechanism can be automatically moved in and out separately from the main tray mechanism section 200 described above.
This is because it is possible to prevent the disc 201 from accidentally falling into the main body when the disc 00 is pulled out, and it is possible to take the disc 201 in and out when it is pulled into the main body.

The seventh point also concerns the auxiliary tray mechanism section, and the disc search performance mechanism section 400 does not enter the driving state until after the auxiliary tray 301 is completely pulled into a predetermined position within the main body by the auxiliary tray drive mechanism 350. The following points can be mentioned.

In other words, this may occur if the disc search performance mechanism section 400 is activated when the auxiliary tray 301 is not in a predetermined position within the main body, such as before or during the retracting operation of the auxiliary tray 901. Malfunction 1
This is because it is possible to prevent the disc 201 stored in the auxiliary tray 301 from being unable to be searched and played.

Next, before explaining the details of the disk search performance mechanism section 400, first, the overall movement process of the f disk 201 during loading and unloading will be schematically explained. That is, in FIG. 19,
01 to Os respectively indicate the locus of the center position during the movement process of the disc 20 which is taken out from the tray main body 202 and loaded into the disc playing mechanism section 700. During unloading, a nearly reverse trajectory is taken to move the disc 20 to the tray. It is housed in the original position of the main body 202.

In this case, when the disc search performance mechanism unit 400 searches for a predetermined disc 201 based on the access information, a disc pushing mechanism, which will be described later, is first driven to push the disc 201 up by 02 mt. Then, the peripheral edge of the disk 201 comes into contact with rollers 611 and 631 of the first and second loading sections 610 and 630 for loading and unloading of the disk transfer viewing section 600, respectively. Here, the first and second loading sections 610 and 630 rotate the rollers 611 and 631 counterclockwise in the figure while moving along the guide rail 650 (
Since the disk 201 is moved in the direction K1), the disk 201 is loaded in the direction of the arrow (K1) while rolling clockwise in the figure. When the disk 201 rolled by the first and second loading sections 610 and 630 passes over the disk loading slot section 651, the disk 201 rolls over the disk loading slot section 651. It is separated from each of the rollers 611 and 631 and reaches a disk accommodating section, which will be described later, due to its own weight.

At this time, the passage of the disc 201 is detected by a disc detector 652 installed in the slot part 651, and in response to this disc passage detection, a disc playing mechanism part 700, which will be described later, is driven. Then, the disc is played.

In this situation, the above disc player +1! i part 70
When the disc playing operation of No. 0 is completed, the disc moving mechanism section 600 is driven in reverse.

3 in the axial direction, this can be done reliably and quickly. Therefore, the overall controllability in relation to each part of the disk search section 500 is improved, and the replacement speed of the disk 201 is improved. This is because it can contribute.

Second, regarding the disc search section 500, when the disc search performance mechanism is driven to a predetermined state and positioned relative to the tray main body 202 (or auxiliary tray 301), first the search wire drive mechanism is activated. One point is that the disk lifting mechanism 510 is operated to push up a predetermined disk 201 after the brake is applied.

According to this, the disc search performance mechanism section 40
0 is positioned relative to the tray body 202 (or auxiliary tray 3θ1) and then the disc 20 is taken out 7, so the disc pushing up mechanism 5
This is because the predetermined disk 201 can be reliably ejected without the disk 10 malfunctioning.

The third point is regarding the disk pushing up mechanism for taking out the disk 201 from the tray main body 202 (or the auxiliary tray 30). Stop part 216 (or (-
1: Auxiliary tray 30] is constructed so that it can be stopped in correspondence with the locking portion 381) of the auxiliary tray 30.

That is, according to this, when the push-up lever 517 is in the push-up state (that is, the performance IJ function state), the tray main body 20
2 (or the auxiliary tray 30)) is reliably prevented from coming off, erroneous operations can be reliably prevented.

The fourth point is regarding the disk transfer mechanism section 600, in which the first and second loading sections 610 and 630, which load and unload the disk 201, are connected to each other via links such as the link lever 676 and the timing belt 669. One point is that the motor 660 is connected to operate in a predetermined state.

That is, according to this, the first and second loading parts 6'+ 630 are driven in an interlocking manner by the same motor 660, so reliable control can be performed with a simple configuration, and the device can be made smaller. This is because it can contribute to effective promotion of power saving.

As for the fifth point, regarding the disc playing mechanism section 700, a disc guide section 724 and a disc ticket section 729 in which the disc 201 transferred by the disc transport mechanism section 600 is accommodated are provided so as to be able to move in and out of the turntable 72, respectively. The disc 201 is moved along with the disc guide part 724 and the disc pocket part 729 to the turntable 721 and is mounted thereon so that it can be played.

According to this, when the turntable 79 is loaded with 20 discs housed in the disc guide part 724 and the disc pocket part 229? This is because by attaching the disc 201 so that it can be played, it can contribute to protecting the disc 201 and effectively promoting miniaturization of the device.

As a sixth point, regarding the disc search performance mechanism section 4θ0, the passage of the disc 201 is detected by the first disc detector 65.
2, and the second disk detector 734 detects whether or not the disk 201 is accommodated in the disk pocket portion 729, thereby controlling each portion to a predetermined state.

That is, according to this, each part is controlled in a state in which the disc 201 is detected in two stages in the transport path such as the loading path 655 and the disc pocket part 729, so that if there is a power outage while the disc is being played, for example, This is because it can contribute to improving safety by preventing malfunctions such as when transferring the next disc 201 to the disc playing mechanism section 700.

It goes without saying that the present invention is not limited to the embodiments described above and illustrated, and that various modifications and applications can be made without departing from the gist of the invention.
